MACHINE FOR MAKING BERRY-BOXES.

Specification of Letters Patent.

Patented July 16, 1907.

Application tiled July 31, 1905. Serial No. 271,987.

To all lwhom it may concern:

Be itknown that I, .losurn E. LYNAM, a citizen of the United States, residing in San Jose, in the county of Santa Clara and State of California, have invented new and useful Improvements in Machines for Making Berry-Boxes, of which the following is a specification.

My invention relates to machines for manufacturing berry boxes, preferably from a singe piece of veneer-or thin box material and has for its object to provide a box or basket in which the bottom is raised so as to permit of the free circulation of air entirely around the box and especially when the boxes are placed one upon another, and thereby avoid the liability of the fruit spoiling from the lack of ventilation as is the case with boxes or baskets made from such chips in the usual manner. I accomplish this object by cutting the bottom portion of the chip loose from the remaining portion7 preferably in connection with the ends of the central or middle portion, and raising it the desired distance before the ends yoi the middle portion are fastened to the endpieces of the sides of the box.

With this and other objects in view my invention consists in the improved construction and novel arrangement of parts of a machine as will be hereinafter more fully set forth.

The accompanying drawings illustrate the invention:--

Figure l is a side-elevation of the machine. Fig. 2 is a front-view on an enlarged scale, showing the end and lower portion of the stationary-frame broken away; Fig. 3 is a side-view of the machine on the same scale as Fig. with parts broken away. Fig. 4 is a front-view of the cutting and folding mechanism showing those parts at the highest part of their movement and the former in position under the blank-carrier. Fig. 5 is a side-view taken from the left side of Fig. 4. Fig. G is a top-view of the stationary cutting-plate over the former, showing a portion of the traveling blank- Carrier and a blank in position. Fig. 7 is a top-view of the endless traveling blank-carrier, the stationary cutting-plate between the former and the cutting and folding devices, and the slidable bridge on which the blank is `carried to its position over the formen Fig. 8 is a side-view, on an enlarged scale, of the mechanisinthat rotates the formers and discharges the finishedbasket. Fig. 9 is a plan or top-view of one of the stitchers or staple forming and driving-devices, and the operating mechanism. Fig. 10 is a front-elevation on an enlarged scale of the reciprocating cutter-head and the devices that fold the sides and ends of the blank. Fig.'1l is a top-view of the stitchers, showing their position with relation to the former when the staples are being driven in both ends of the basket. Fig. l2 is a side-view of the reciprocating, cutting and folding head showing the folder on one side removed from `the head. Fig. 12L is a view of the folder. Fig.

I3 is a front-view of the head showing the cutters removed and the folders and strippers in place. Fig. lll is a plan of the blank-showing the parts that form the sides separated from the bottom and ends. Fig. l5 is a transverse sectional-view of the finished box.

Referring more particularly to the drawings l indi- Cates a frame at the upper portion of which are mounted the motor-shaft 2 and the operating shaft 3. Reciprocally mounted upon the frame is a plunger which is adapted to be moved toward and from a series of formers 4 mounted at the extremities of the spokes of a wheel 5. The plunger' is composed of two side rods 6 which reciprocate in bearings in brackets 7 projecting inwardly from the sides of the frame and two heads or blocks 8 and 9, and it is driven by means of a cam 10 on the shaft 3, as shown more particularly in Figs. 2, 4 and 5. On two sides of the plunger opposite each other blades or cutters llare arranged in position for engagement with and cutting the chip 'or blank l2 into three pieces, preferably lengthwise of the blank as shown by full lines in Figplf/i. After the blanks have been cut in this manner they are carried to the former l 4 in position to be bent into the desired shape. Two sides of the former are each provided with ribs or raised portions li which virtually form a recess in the bottom of the former which is as deep as it is desired to have the bottom raised in the completed box, and into which recess the central portion is forced or carried by two followers or strippers l5. The followers l5 are arranged on the plunger between the cutters il in position for forcing the central portion of the blank into the recess.

Two blades ll.1 are each rigidly secured between a recessed block 4 and the inner face of one end of the head 9 so as to be movable with the head and fold the ends of the middle strip of material over two of the edges of the former 4. A stem l5 from each stripper l5 extends through the block 4* and through a spring l52 seated in the recess of the block. A pin l53 projects through the stem and engaging with the lower end of the spring 152 compresses the spring when forced inward by the stripper engaging with the material and forcing it between the ribs 14 or into the recess in the head. When the plunger rises after having folded the material upon the foi-mer the compressed springs force the stems out and thereby hold the strippers against the bottom of the box until after the blades lll have been Withdrawn from engagement with the material, and thus prevent the accidental movement of the box on the former bythe friction of the blades with the material in being withdrawn.

The cutters ll are mounted upon a head 1G at the end of a short rod or stem I7 which is adapted to be moved back and forth through a collar 1S on the plungerhead 9. The head engages with thc ends of the block 4l and is guided thereby and it is locked so as to be moved rigidly with the plunger during a part of its movement by means of a pin 19 which engages with a shoulder at the lower end of a lever 20. The upper portion of the lever is provided with an inclined face or shoulder 2l which is adapted to engage with a stop 22 on one of the brackets 7 and swing the lever` upon its pivot so as to throw the shoulder at the lower end out of engagement with the pin, and thereby permit the knives to stop before they engage with the former while permitting the forward movement of the plunger l to complete the formation of the box` A stop 161 engages with a cutting-plate 50 and prevents the cutters from striking the formers 4.

On the rip-stroke of the plunger the upper end of the stem 17 engages with a bridge or cross piece 71 and forces the parts into their normal position where they are held by the rengagement of the shoulder with the pin 19 when the lever is automatically swung over by the spring 23. Fingers 24 at the ends of the plunger 9 engage with the sides of the blank 12 and carry them down onto the former in position to be engaged by clamps 25. The fingers are preferably notched or provided with shoulders 241 for engaging with the edges of the side-strips of material and holding them upon pins 51 on the former in their correct position relative to the bottom or middle-piece. After the severed pieces of the blank have thus been 'carried forward and pressed upon the former 4 with the central portion at the desired distance in advance or forward of the lower edges that form the bottom of the box, the ends of the pieces are folded inward by two levers 26 so as to overlap each other; said leversbeing adapted to engage with the clamps 25 and swing them from the open to the closed position, as shown in Figs. 3 and 5. lhe clamps are preferably provided with rollers 27 with which the lower ends of the levers engage, while the upper ends of the levers are each connected with a spring 28 for Ygiving the levers a yielding engagement with the clamps the tension of the springs being regulated by means of screws 29. Each of the levers 26is pivotally mounted at the lower end of a lever 30, which is pivotally mounted at 31 to the upper head 8 of the plunger, and with its upper end provided with an anti-friction roller 301 in position to be engaged by cams 32 on the shaft 3. The cams 32 are secured to the shaft 3 so as to stand opposite to each other, and the upper ends of the levers are connected by a spring 33 which normally holds them toward each other and causes their lower ends to hold the levers 26 out far enough to avoid engagement with the clamps 25when theplunger is moved downward.

The cams are arranged a trie out of diametrical alinement as shown in Fig. 5, so that one of them will engage with the roller 301 at the top of its lever and move one lever an instant before the other one moves, so as to bend the ends of one side of the box in advance of the ends of the other side and thereby prevent any possible conict between the ends as they are being bent in upon the former. The ends of the middle portion are bent in advance of either of the side-pieces, so that when the ends are stitched together as shown at 34 the side ends will overlap the ends of the middle portion and each other in the usual 'manner The folding levers 26 are adjusted by screw stops 95 on the levers 30.

The clamps 25 are provided with curved links 35 at their pivotal edges which extend below the pivots and are connected by means of a spring 36. The links and springs are so arranged that normally the pivotpoints are below the hinges of the clamps and hold the clamps in their open position, but as soon as the clamps have been forced inward by the levers 26 said pivot points will pass above the hinges and the spring will be drawn up nearly into a line with the hinges and will then hold the clamps in their closed position.

The chips or blanks l2 are carried into their position over the former by means of an intermittently movable y carrier which preferably consists of two chains 37 passing over wheels 38 and 39. The inner or adjacent sides of the chain are provided with substantially U-shaped clips 40 for the reception ofthe ends of the blanks, a stud or support 41 on each clip preventing the blank from falling from the chains. The upper portion of the carrier is arranged to travel on top of a series of strips 42 on the frame 1 and the lower portion of the carrier preferably runs through guides 43. The chains are held under proper tension at all times by means of springs 44 which engage with pivoted arms 45 in which the stud axles of the wheels 38 are mounted.

In feeding the chips to the machine, they are taken one at a time from a pile 46 by an attendant and placed on the clips 40 of the chains by which they are carried forward by the intermittent movement of the carrier. The inner strips 42 terminate at a short distance from the former 4 and are arranged at a distance apart for the reception of what 1 shall call a bridge 46 which is slotted at its forward end for the passage of oneof the clamp-closing levers 26 and is reciprocated between the strips 42 `by means of a cam 461 on a shaft 47 which operates the stitch-forming mechanism. Every time the shaft makes a revolution a box is completed and the arm is caused to engage with a lever 48 pivotally secured to the underside of the table and reciprocates the bridge by means of a link 49 shown in dotted lines in Fig. 7. The bridge moves forward simultaneously with the movement of the chip and -prevents it from engaging with the cutting-plate 50 which is secured at its ends to the sides of the frame, and is immediately returned ito its normaLposition by a spring 481 as soon as the cam 461 passes beyond the end of the lever 48. As soon as the blank has been placed over or upon the plate the plunger descends and the knives cut it into three pieces along the lines 13 and the central portion passes down through an opening 5l in the plate and the side-pieces fall over the sidos of the plate into the spaces between the clamps 25 and the former 4 and the pieces are then all bent into shape and held there by the clamps until'stitched and nally discharged.

The carrier is driven by means of a shaft 52 which actuates the shaft of the wheels 39 at one end and is actuated by a gear-wheel 391 on the axle of the wheel 5 at the other. The wheels 5 and 391 are given an intermittent motion by means of a lever 53 which is pivotally mounted on one side of the frame l with its upper end engaged or actuated by a cam 54 on the shaft 3. A link 55 is pivotally connected with the lower end of the lever and with a block 56 which is pivotally connected with an arm 57 extending out from the axle of wheel 5 and the block is provided with a hook 59 which is adapted to engage with recesses 60 in the periphery of a disk 58 on said axle.

soes

bracket arm 6l is secured to the block, and between it and the arm 57 is a spring G2. A stop or detent G3 is pivotally mounted on the base of the frame in position to have its nose or free end automatically drawn into one of the recesses 60 by a spring 64 and thereby hold the disk and wheels against rotation.

The stop is provided with an arm or projection G5 which extends into the path of and is adapted to be engaged by the roller-stud 531 on the lower end of the lever 53 when the lever is operated preparatory to rotating the disk 58 and Wheels 5 and 39. When the lever 53 begins to move toward said arm for unlocking the disk the block 56 is swung on its pivot at the end of arm 57 until it engages with a pin 66 during which movement the free end of the hook 59 is withdrawn from its recess 60 which will permit the block and its connected parts to be moved or swung over the desired distance without rotating the disk. .l ust before the lever reaches the limit of its movement it engages with the projection G5 and withdraws the stop or detent G3 from its recess and also moves the end of hook 59 into position for engaging with a new recess in the disk. On the return movement of the lever the spring G4 will cause the hook to engage with the recess in the plate as soon as the pull of the lever is released and the disk will thereby be carried back into its normal position and the wheels 5 and 391 will be given a partial rotation and the detent will have been permitted to engage with the edge of the disk and will be drawn into a recess by the spring 64 as soon as the movement of the lever is completed. This movement of the wheel 5 will carry forward the former 4 whichhas previously been located under the plunger `and place the box in position at the stitch-forming stitching mechanism mayjbe of any desired form of construction and forms no part of this invention and is therefore not more particularly described and as there aretwo of them,r one for each end as shown in Figs. 9 and ll, the mechanism ,for operating them is also arranged in duplicate, and the description of one will be applicable to the other. ln their normal position as shown in Fig. 9 the stitchers are so located as not to be in the path of the arms of the wheel 5, but as soon as the arm with a box thereon is moved into position the stiteher is swung into its operative position as shown by dotted curved lines in Figs. 9 and ll, with its nose or inner portion between the side of the former and the ends of the box as shown in Fig. ll.

The stitcher is moved by means of a spring 69 engaging with one arm of an angular-lever 70 which is pivotally connected with a projection 7l on the stitcher. This movement of the stitcher causes a stud 72 on the outer end of its plunger 73 to enter a recess 74 at the i'ree end of an arm 75 so that as soon as the arm is moved inward by a cam 76 on the shaft 47 the plunger 73 will be driven in and the ends of the basket secured together by means of the stitches 34. The arm 75 and an arm 77 are pivotally mounted at the upper end of a standard 78 and the arm 77 is provided with two pins 79 and 80, one of which is in the slot of the can 7 G and the other one engages with the arm 75 and forces it back as the pin 79 is moved by the cam 7 6. The arm 77 is extended beyond the pin 79 and has the end of spring 8l connected therewith which will cause the arm 75 to move inward and yet permit of the arm 75 and the plunger 73 stopping in case of an obstruction or failure ot the stitcher to operate, without interfering with the operation of the cam. The tension of the spring Sl. can be regulated by a take-up wheel 82. Each stitcher is returned to its normal position by m cans of a pin 83 which moves in a slot 84 in an extension 85 from thc lever 70 when the arm 75 moves inward but engages at the outer end when the arm 75 moves Outward.

Alter the box has been stitched, which is performed simultaneously with the formation of a new box on the former which has been carried under the cutting and forming mechanism, the wheel 5 is given two partial 1'0- tations or half a revolution which brings the box in position to be discharged over a standard 8G into a spout or trough 87 as shown in Fig. l. Before the box can drop from the former 4 into the trough it is necessary to release the clamps 25 which is done by means of a block 88 shown more particularly in Fig. 8, which is moved between the clamps by means ol' a link 89 connected with the lower end of the lever 53. The block is pivotally connected to the upper ends oi two pivoted arms 90 and when it is carried forward its inclined faces 91 enga-gc with projections 92, one at one end of cach clamp. The projections are preferably movable as in the form of antifriction wheels and are adapted to carry the clamps out far enough, so that the springs 3G will hold them in that position after the block 88 has been withdrawn by the return movement of the lever 53.

As above-described it will be seen that the operation ol' my machine -is substantially continuons and a very desirable box is produced at a minimum of cost. It is also evident that changes or modifications can be made in it and I reserve the right to make all such changes as will come within thescepe ol my invention.
